HOW TO READ EXIT AND ENTRANCE POLLS: The first column of numbers in each table shows how many voters fall into each category; those numbers should be read down. The remaining figures show how each category voted; those numbers should be read across.

Exit polls are a survey of selected voters taken soon after they leave their voting place. Pollsters use this sample information, collected from a small percentage of voters, to track and project how all voters or a specific segments of the voters sided on a particular race or ballot measure. Because of the nature of caucuses, these polls are conducted as voters enter a caucus venue and are known as entrance polls.

Candidates who have dropped out of the presidential race may still be included in exit and entrance polls.
